La présente étude est consacrée à la collecte des proverbes moba, une langue Gur du nord du Ghana et du Togo. Elle s’articule autour de la question suivante : Comment collecter le maximum de proverbes tels que utilisés par les locuteurs ? Elle est inscrite dans la démarche éclectique du philosophe de Potamon d'Alexandrie qui préconise l’emprunt aux divers systèmes leurs meilleures thèses conciliables et innovantes. A cet éclectisme, il faut ajouter que la prise en compte de toutes les couches sociales ainsi qu’une confiance permanente entre enquêteur et enquêtés ont constitué une condition nécessaire pour atteindre les objectifs escomptés. La collecte des proverbes moba a nécessité une préparation à la fois théorique et matérielle. The focus of this study is the collection of Moba proverbs, a Gur language from northern Ghana and Togo. It is structured around the following question: How to collect as many proverbs as possible as used by the speakers? It is in line with the eclectic approach of the Potamon d'Alexandrie philosopher who advocates borrowing from the various systems their best reconcilable and innovative theses. To eclecticism, it must be added that taking into account all social strata as well as a permanent trust between interviewer and respondents was a necessary condition to reach the expected objectives. The collection of the moba proverbs required both theoretical and material preparation. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0720/a.php" alt="Hit counter" /></p>

The Impact

Abstract Background The adoption of climate-smart agricultural (CSA) practices is expected to improve farmers’ adaptation to climate change and also increase yields while simultaneously curbing greenhouse gas (GHG) emissions. This paper explores the determinants of smallholder farmers’ participation in GHG-emitting activities. It also estimates the impact of CSA activities on reducing GHG emissions. Methods The findings are based on survey data obtained from 350 smallholder farmers in the East Gonja district of Northern Ghana. We adopted the generalized Poisson regression model in identifying factors influencing farmers’ participation in the GHG emission practices and inverse-probability-weighted regression adjustment (IPWRA) to estimate the impact of CSA adoption on GHG emissions. Results Most farming households engaged in at least one emission activity. The findings of the generalized Poisson model found that wealthier households, higher education, and households with access to extension services were less likely to participate in GHG emission activities. There was also evidence that CSA adoption significantly reduces GHG emissions. Conclusion Advocacy in CSA adoption could be a necessary condition for environmental protection through the reduction of GHG emissions.

Poverty Levels

Globally, addressing poverty levels and inequality remained one of the topmost priorities and has been accorded the first position in the Sustainable Development Goals (SDGs). Although Ghana as a whole is faring well in poverty reduction over the past decades, poverty levels and inequalities remains high in the northern parts. This study analysed the gendered welfare gap and the effects of climate change and livelihood diversification on the welfare gap. Through multistage sampling, 432 households were selected and interviewed using a questionnaire. A selectivity bias corrected Oaxaca Blinder model was estimated using household per capita consumption expenditure as a measure of households’ welfare. The result shows that there is a significant welfare gap of $45.85 (GH₵211.85), an equivalent of 11.4% between male headed and female headed households. Controlling for selectivity bias revealed that the observed gender welfare gap was underestimated. Livelihood diversification had positive significant effect on the explained component of gender welfare gap. Climate change/variability had positive significant effect on welfare gap through the explained component and a negative significant effect through the unexplained component. Therefore, observed climate change and variability led to an increase in gender welfare gap by 64.62%, while the unobservable returns from climate factors contributed to a reduction in gender welfare gap by 193.26%. Since addressing unobservable climate factors is limited, there is the need to improve the climate characteristics of women. Although livelihood diversification is a necessary condition, policies such as training and education that would ensure that females also have higher returns from such strategies are sufficient to address gender welfare gaps. To improve the welfare of farmers in the midst of climate change, animal rearing should be promoted among maize crop farmers. Similarly, government’s policy of one district one factory should consider improving agro-processing opportunities in the region into commercial activities.

The Origin Of Life

AbstractFor life to develop, planets are a necessary condition. Likewise, for planets to form, stars must be surrounded by circumstellar disks, at least some time during their pre-main sequence evolution. Much progress has been made recently in the study of young solar-like stars. In the optical domain, these stars are known as «T Tauri stars». A significant number show IR excess, and other phenomena indirectly suggesting the presence of circumstellar disks. The current wisdom is that there is an evolutionary sequence from protostars to T Tauri stars. This sequence is characterized by the initial presence of disks, with lifetimes ~ 1-10 Myr after the intial collapse of a dense envelope having given birth to a star. While they are present, about 30% of the disks have masses larger than the minimum solar nebula. Their disappearance may correspond to the growth of dust grains, followed by planetesimal and planet formation, but this is not yet demonstrated.

Scanning Electron

The environmental scanning electron microscope (ESEM) has evolved as the natural extension of the scanning electron microscope (SEM), both historically and technologically. ESEM allows the introduction of a gaseous environment in the specimen chamber, whereas SEM operates in vacuum. One of the detection systems in ESEM, namely, the gaseous detection device (GDD) is based on the presence of gas as a detection medium. This might be interpreted as a necessary condition for the ESEM to remain operational and, hence, one might have to change instruments for operation at low or high vacuum. Initially, we may maintain the presence of a conventional secondary electron (E-T) detector in a "stand-by" position to switch on when the vacuum becomes satisfactory for its operation. However, the "rough" or "low vacuum" range of pressure may still be considered as inaccessible by both the GDD and the E-T detector, because the former has presumably very small gain and the latter still breaks down.

Complexity of modern metallurgical plants, presence of great number of horizontal and vertical interactions between their various structural subdivisions makes it necessary to apply a systems analysis to elaborate effective measures for stable development of a plant operation. Among such measures, digitalization of a plant is widespread at present. To implement the digitalization it is necessary to have clear vision about links at all the levels of the technological system of a plant. A terminology quoted, accepted in the existing regulatory documents for defining of conceptions, comprising the technological system. It was shown, that the following four hierarchical levels of technological systems are distinguished: technological systems of operations, technological systems of processes, technological systems of production subdivisions and technological systems of plants. A hierarchical scheme of technological systems of hot-rolled sheet production at an integrated steel plant presented. Existing horizontal and vertical links between the basic plant’s shops shown. Peculiarities of flows of material, energy and information at the operation “rolling” of the technological system “hot rolling of a steel sheet” considered. As a technical system of the technological process of the hot rolling, the hot rolling mill was chosen. A structural diagram of the hot rolling mill was elaborated, the mill being consisted of reheating furnaces, roughing and finishing stand groups, with an intermediate roll-table between them, and down-coilers section. Since the rolling stands are the basic structural elements of the hot rolling mill, structural diagrams of a roughing and a finishing stands were elaborated. Results of the systems analysis of the technological and technical systems, hierarchically linked in the process of steel sheet hot rolling, can be applied for perfection of organization structure of the whole plant, as well as for elaboration mathematical models of a system separate elements functioning, which is a necessary condition for a plant digitalization.

The removal of slag from melt surface of hot metal and steel ladles is a necessary condition to provide a deep desulphurization and dephosphorization of hot metal and steel in the process of their processing. A review of methods of slag skimming presented, mainly based on slag mechanical shoveling and its removal out of ladles by vacuum sucking. It was shown, that manipulators design for the slag skimming working instrument moving depends on the production scale, mass of the processed heats, amount and properties of the slag to be removed, production process intensity and ecological requirements. Peculiarities of designs and technical parameters of machines for slag skimming presented, designed by Irkutsk plant of heavy machinery, Scientific and Production Enterprise n.a. M.I. Platov, VNIIMETMASH, Kuznetsk and Novolipetsk steel plants. Technological methods of control of slag composition and physical properties considered, first of all of viscosity and fluidity, which have significant effect on selection of a method of slag skimming. Advantages and drawbacks of actions, aimed at more complete slag removal from metal surface by a scraper noted including bath blowing off by an inert gas, liquid slag tapping into am intermediate settling tank following its removal into a slag bowl. In case of satisfactory fluidity it is possible to slag removal by vacuum sucking, which at the same time promoted the melt degassing. Work done in this area abroad noted. Methods of vacuum slag removal developed in the USA and Japan described.
